Taking CNKI and web of science database as data sources, a bibliometriccomparative analysis was carried outon the study of land-surface evapotranspiration in the Yangtze River Basin and that of domestic and foreign countriesby using CiteSpace information visualization software. The results showed that from 1992 to 2020, 5216 articles on land-surface evapotranspiration were published at home and abroad, including 179 articles in the Yangtze River Basin. The number of articles in Chinese and English showed an increasing trend before 2016. In the study of land-surface evapotranspiration in the Yangtze River Basin, Nanjing University of Information Science and Technology, Hohai University and Nanjing Institute of Geography and Limnology, Chinese Academy of Sciences ranked among the top three research institutions. These research institutions mainly rely on the measured evapotranspiration data and meteorological data provided by their subordinate experimental stations to carry out evapotranspiration simulation and verification research. The research content focuses on evapotranspiration acquisition and numerical simulation, followed by the analysis of land-surface evapotranspiration change mechanism and temporal and spatial evolution process, while there are relatively few studies on the eco-environmental effects of land-surface evapotranspiration change. From the highly cited trend, it can be found that with the continuous improvement of the estimation accuracy of land-surface evapotranspiration, scholars gradually pay attention to the study of evapotranspiration components. In terms of change mechanism, there are many studies on the impact of environmental factors on land-surface evapotranspiration in the Yangtze River Basin, but there are few studies on the impact of land use, surface cover, vegetation type and other underlying surface properties and changes on evapotranspiration. The effect analysis of evapotranspiration mainly focuses on the impact of land-surface evapotranspiration on water balance, wetland treatment and crop yield.
